Identification
Name:Hydrogen peroxide
Description:Hydrogen peroxide (H2O2) is the simplest peroxide (a compound with an oxygen-oxygen single bond). It is also a strong oxidizer. Hydrogen peroxide is a clear liquid, slightly more viscous than water. The oxidizing capacity of hydrogen peroxide is so strong that it is considered a highly reactive oxygen species. Organisms also naturally produce hydrogen peroxide as a by-product of oxidative metabolism. Consequently, nearly all living things (specifically, all obligate and facultative aerobes) possess enzymes known as catalase peroxidases, which harmlessly and catalytically decompose low concentrations of hydrogen peroxide to water and oxygen. (Wikipedia) Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colourless in a dilute solution, slightly more viscous than water. It is a weak acid. It has strong oxidizing properties and has also found use as a disinfectant and as an oxidizer. Hydrogen peroxide (H2O2) is a well-documented component of living cells. It plays important roles in host defense and oxidative biosynthetic reactions. In addition, there is growing evidence that at low levels, H2O2 also functions as a signaling agent, particularly in higher organisms. (HMDB) In E. coli, H2O2 is used in the aerobic degradation of L-ascorbate, and produced as a byproduct in many reactions involving oxygen as an oxidizing agent. (EcoCyc) In E. coli glyoxylate metabolism, H2O2 is produced as a byproduct of the conversion of glycolate to glyoxylate by the enzyme glycolate oxidase (EC 1.1.3.15), and H2O2 is then converted to harmless O2 by the enzyme catalase (EC 1.11.1.6).
